  • AS3 trouble instantiating Document Class of loaded SWF

    - by Marcy Sutton
    I am loading one swf into another using the Loader class, but when the child swf finishes loading and is added to the display list, its Document Class is not instantiated. I have a few trace statements should execute when the object is created. When I compile the child SWF on its own, the Document Class runs as expected. So I'm wondering... how do I associate a child SWF's Document Class with Loader.content? // code in parent SWF's Document Class (Preloader) public function Preloader(){ swfLoader = new Loader(); swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderDone); swfLoader.load(new URLRequest("mainmovie.swf")); } private function loaderDone(e:Event):void { // Add Loader.content to new Sprite mainMovie = Sprite(e.target.content); mainMovie.alpha = 0; swfLoader = null; addChildAt(mainMovie, 0); mainMovie.addEventListener(Event.ADDED_TO_STAGE, mainMovieAddedListener); } // functions in MainMovie.as not ever running, // even though it is listed as the child SWF's Document Class Cheers!

  • How do you get "in the zone"?

    - by Wayne Werner
    Hi, I've just started my first real programming job and am pleased to discover that this is exactly what I want to do for the rest of my life. When it comes round to ~1 hour before it's time to go home and I think "Man, do I have to go home already?" I'd say that's A Good Thing(tm). One thing I've discovered though is that it takes a little while for my brain to get "in gear" or "in the Zone", so I'm curious what other folks do to get programming at their prime. My current flow is when I get here I visit SO and look at the interesting problems - I find it helps get my brain moving. After 20-30 minutes I start looking at my code/specs/etc to decide what I want/need to work on first. So how do you get started?

  • Is it practical to learn and use Forth?

    - by Workshop Alex
    When I was still a young developer, I started to focus on the many available programming languages. But in 1980 to 1990 there weren't many freely available compilers. So I started with several BASIC dialects for home computers, Pascal and C on my PC, I did an exam in COBOL and dabbled a bit in Assembly and a few other languages. And at one point I took a short look at Forth. That's over 20 years ago and I've learned a lot ever since. I know that Forth is still used these days. It's still a good programming language but since I focus mostly on Windows development, I just wonder if knowing Forth could be helpful for future projects of mine. So, would it be practical for an experienced developer to learn more about Forth?

  • Can someone please explain to me the basic function of Intents in the Android OS?

    - by K-RAN
    I'm new to programming applications for the Android OS. As far as general architecture of the OS goes, I understand that processes are implemented as Linux processes and that each one is sandboxed. However, I'm utterly confused on the IPCs and syscalls (if any) used. I know that the IBinder is a form of this; parcels are sent back and forth between processes and Bundles are array forms of parcels (?). But even that is still unfamiliar to me. Same with Intents. All in all, I don't understand what kinds of IPCs are implemented and how. Could someone briefly explain to me the specific methods used by user level applications in Android OS to communicate with each other and the OS? I've done kernel programming and played with various IPCs in Linux (Ubuntu and Debian) so it would help immensely if this was all explained in relation to what I'm familiar with... Thanks in advance!

  • Place JComponent On The Top Of JXLayer

    - by Yan Cheng CHEOK
    Hello, currently, I had successful applying JXLayer on my charting component, to draw a yellow information box on the top of it. final org.jdesktop.jxlayer.JXLayer<ChartPanel> layer = new org.jdesktop.jxlayer.JXLayer<ChartPanel>(this.chartPanel); this.chartLayerUI = new ChartLayerUI<ChartPanel>(this); layer.setUI(this.chartLayerUI); At the same time, I wish to add the following JComponent (DefaultDrawingView) on the top of JXLayer. This JComponent has the ability 1) To receive mouse event to draw figures on itself. Within ChartLayerUI, I add the following code @Override @SuppressWarnings("unchecked") public void installUI(JComponent c) { super.installUI(c); JXLayer<JComponent> l = (JXLayer<JComponent>) c; l.getGlassPane().setLayout(new java.awt.BorderLayout()); // this.view is DefaultDrawingView drawing object. l.getGlassPane().add(this.view, java.awt.BorderLayout.CENTER); } However, after having the above code, I get the following outcome 1) My charting component ChartPanel are being blocked by DefaultDrawingView 2) My charting component no longer able to receive mouse event. What I wish is that A) ChartPanel and DefaultDrawingView able to show up B) ChartPanel and DefaultDrawingView able to receive mouse event Is there other steps I had missed out, or did wrong? Thanks.

  • Issuing native system commands in Scala

    - by Tony
    I want to issue a native system command from a Scala program, and perhaps trap the output. ("ls" comes to mind. There may be other ways to get directory information without issuing the command, but that's beside the point of my question.) It would correspond to os.system(...) in Python. I've looked in "Programming in Scala". I've looked in O'Reilly's "Programming Scala". I've Googled several combinations of terms. No luck yet. Can someone out there give me an example, or point me at a resource where I can find an example?

  • Best computer-science universities in Europe?

    - by Tom
    I am in 11th grade and only one year left when I finish my school. I am sure I want to dedicate my life to programming. In my country the education's level is not so high as in Europe, so I want to emigrate and study not just for a diploma, but for knowledge too. So, what universities would you suggest me which has subject Computer-Science? I prefer web programming. Please do not delete this message though it is quite offtopic, but it's the best place for me to get suggestions from advanced programmers who have already finished their university. And I hope here comes also teenagers who can make the best decision choosing university. Thank you. Please read the whole my message before voting to close this thread, thanks.

  • HTML5 audio object doesn't play on iPad (when called from a setTimeout)

    - by Dan Halliday
    I have a page with a hidden <audio> object which is being started and stopped using a custom button via javascript. (The reason being I want to customise the button, and that drawing an audio player seems to destroy rendering performance on iPad anyway). A simplified example (in coffeescript): // Works fine on all browsers constructor: (@_button, @_audio) -> @_button.on 'click', @_play // Bind button's click event with jQuery _play: (e) => @_audio[0].play() // Call play() on audio element The audio plays fine when triggered from a function bound to a click event, but I actually want an animation to complete before the file plays so I put .play() inside a setTimeout. However I just can't get this to work: // Will not play on iPad constructor: (@_button, @_audio) -> @_button.on 'click', @_play // Bind button's click event with jQuery _play: (e) => setTimeout (=> // Declare a 300ms timeout @_audio[0].play() // Call play() on audio element ), 300 I've checked that @_audio (this._audio) is in scope and that its play() method exists. Why doesn't this work on iPad?

  • How to add images while moving finger across UIView?

    - by Luke Irvin
    I am having issues adding an image across a view while moving finger across the screen. Currently it is adding the image multiple times but squeezing them too close together and not really following my touch. Here is what I am trying: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch * touch = [touches anyObject]; touchPoint = [touch locationInView:imageView]; if (touchPoint.x > 0 && touchPoint.y > 0) { _aImageView = [[UIImageView alloc] initWithImage:aImage]; _aImageView.multipleTouchEnabled = YES; _aImageView.userInteractionEnabled = YES; [_aImageView setFrame:CGRectMake(touchPoint.x, touchPoint.y, 80.0, 80.0)]; [imageView addSubview:_aImageView]; [_aImageView release]; } } -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [self touchesBegan:touches withEvent:event]; } Any suggestions is much appreciated. EDIT: What I want: After taking or choosing an image, the user can then select another image from a list. I want the user to touch and move their finger across the view and the selected image will appear where they drag their finger, without overlapping, in each location.

  • Request-local storage in ASP.NET (accessible to the code from IHttpModule implementation)

    - by IgorK
    I need to have some object hanging around between two events I'm interested in: PreRequestHandlerExecute (where I create an instance of my object and want to save it) and PostRequestHandlerExecute (where I want to get to the object). After the second event the object is not needed for my purposes and should be discarded either by storage or my explicit action. So the ideal context where my object should be stored is per request (with guaranteed no sharing issues when different threads are serving requests... or processes/servers :) ) Take into account that actual implementation I can do is being made from a HttpModule and is supposed to be a pluggable solution for already written web apps (so the option to provide some state using static/instance variables in Global.asax doesn't look good - I will have to modify Global.asax on every web application). Cache seems to be too broad for this use. I tried to see whether httpContext.Application (of type HttpApplicationState) is good for me or not, but cannot get whether it is exactly per HttpApplication instance or not (AFAIK you can have several instances of HttpApplications used on different threads and therefore serving several requests simultaneously - then using storage shared between threads will not work correctly; otherwise I would use it because one HttpApplication instance serves exactly one request at a time). Something could be done with storing state on the HttpModule instances if I know for sure that it's exactly bound 1-to-1 with every HttpApplication instance running (but again I need a proof that HttpApplication instance is 1-to-1 with my HttpModule's instance). Any valuable and reputable links on these topics are much appreciated... Would be great to find something particularly well-suited for per request situation (because otherwise I may end up with something ulgy... probably either some 'broader' scoped storage and some hacks to have different keys in the storage for different requests, OR using a thread-local thing and in this way commit to the theory that IIS/ASP.NET will not ever serve first event from one thread and the second event from the other thread and so on)

  • Python 2.6 and 3.1.1, earlier version compatibility

    - by Todd
    I ordered three books to start teaching myself Python - a beginning programming book, a computer science book that uses Python for all of its code references, and a book on Python network programming. Unfortunately, I was a little too quick on ordering them, because I hadn't noticed the version differences. The beginner book is for python 3.1, the CS book is Python 2.3, and the last is Python 2.6. The CS book is also oriented towards beginners. My question is, will the different versions be too different at this level for me to effectively use all three, or will I likely be able to get by learning from the 3.1 beginners book and then sort of teach myself from the 2.3 CS book, and be able to comprehend 2.6 code? That probably didn't make sense. I hope it did.

  • Integrate Python Projects Into Xcode

    - by Vynile
    Hi! I'm a Mac user, and one of my hobbies is programming. I use Xcode, the integrated IDE of Mac OS X. I started to learn Python programming langage, and I want to use Xcode for developing my scripts. I searched for weeks in the internet, but I didn't find something interesting. Firstly, I want to update the integrated interpreter of Mac OS X, that is on 2.6 version. And secondly, I want to create a Python project on Xcode easily, like I do with C & C++ projects. Can you help me? I really need help! Cordially.

  • Is it any desktop wysiwyg editors for mediawiki / wiki available?

    - by Eye of Hell
    Hello. Mediawiki is very good, but for programming tasks editing it via web is not very handy since wysiwyg is very limited, pressing 'edit' + 'publish' on any small change and waiting for page loading kins of annoying. I have seen alot of desktop wikis (personal wikis) that are free from such problems. The best example is a 'wikidpad' that has a usage patter of 'focus, edit wiki in-place, minimize'. This is very handy for programming work where you need to make small changes to wiki and documentation during development, and documentation is written much more often than readed :). But all such desktops wikies are personal - they don't have any wiki sharing (or marginally limited support for it). So, maybe it's a desktop application exists that can connect to mediawiki and allows to view and edit it via a rich wysiwyg editor? Any hints are welcomed.

  • Is Python appropriate for algorithms focused on scientific computing?

    - by gmatt
    My interests in programming lie mainly in algorithms, and lately I have seen many reputable researchers write a lot of their code in python. How easy and convenient is python for scientific computing? Does it have a library of algorithms that compares to matlab's? Is Python a scripting language or does it compile? Is it a great language for prototyping an algorithm? How long would it take me to learn enough of it to be productive provided I know C well and OO programming somewhat? Is it OO based? Sorry for the condensed format of questions, but I'm very curious and was hoping a more experienced programmer could help me out.

  • Best anti boss tricks to hide your private page navigation from your desktop.

    - by systempuntoout
    This question is slightly related to programming and it's kinda lame, i know; but i saw many funny things in these years and i'm looking for new tricks from you. I'm talking about methods to fast-hide\camouflage not job related web pages on your desktop when boss arrives like a ghost\ninja behind your shoulders. I know how much can be frustrating, programming hard for ten hours and then been caught by your boss watching XKCD during a 2 minutes break. I think the most common anti boss trick is the evergreen CTRL+TAB, but you have to be fast and your left hand has to be near the keyboard. I saw pitch black brightness on Lcd (how can you pretend to program on that?) or custom sized browser to fit a little space just below the IDE. My favourite one at the moment is using fire gesture plugin with FF; with a micro gesture you can hide FF to your tray in a blink of an eye. Do you have any trick to share?

  • Where can I learn more about datastructure tricky questions?

    - by Sandbox
    I am relatively new to programming (around 1 year programming C#-winforms). Also, I come from a non CS background (no formal degree) Recently, while being interviewed for a job, I was asked about implementing a queue using a stack. I fumbled and wan't able to answer the question. After, the interview I could do it(had to spend some time). I have learnt (and think that I know it well) basic algorithms in datastructures using the book Data Structures: A Pseudocode Approach with C - Richard F. Gilberg (Author) . I want to know about sites/ books which have such questions along with answers. I think this will allow me to develop my CS specific problem solving skills. Any help is appreciated. BOUNTY: I am looking at some blog/website with datastructure and algorithms Q&A.

  • Caffeine and Stimulant Usage

    - by Jon Purdy
    Let's see how many of us fit the old stereotype, shall we? Do you typically use caffeine when programming? During the day or at night? How frequently do you pull all-nighters? Do you use caffeine when you do stay up late? Do you prefer to have a large amount of caffeine all at once, or small amounts over a longer period of time? Do you use energy drinks, 5-hour energy shots, coffee, tea, or caffeine pills? How about other stimulants such as amphetamines? For instance, I've known a programmer who dabbled in speed because they believed it increased their ability to focus on programming, though happily they're clean now and quite honest about the whole experience. Share, discuss, find the Ballmer Peak of caffeine, enjoy. Happy Easter.

  • Details View and integration with TinyMCE <%@ Page validateRequest="false" %>

    - by GibboK
    I use TinyMCE in a DetailView in in EDIT MODE. I would like to know if there is a solution which can prevent Request Validation to trigger an error WITHOUT USING <%@ Page validateRequest="false" %> for my page. The only way I found out at the moment is to encode TextBox used by TinyMCE using option: "xml" tinyMCE.init({ encoding: "xml", In this way Request Validation does not trigger error but at the time to read the data in the TextBox the result it is Encoded. I also tried to Decode on PageLoad the content of the TextBox using this code myTextBox.Text = HttpUtility.HtmlDecode(myTextBox.Text) But the result is not as expected, so I can visualize it just Encoded text. Any Ideas? Thanks UPDATE I found a solution to my problem. I added in _DataBound event for the DetailsView this code TextBox myContentAuthor = (TextBox)uxAuthorListDetailsView.FindControl("uxContentAuthorInput"); myContentAuthor.Text = HttpUtility.HtmlDecode(myContentAuthor.Text); So on DataBound event, (should work even on post back) the content will be decodene for textbox tinymce. Here how should work: 01 - TinyMCE ESCAPE data inserted in textbox using function encoding: "xml", 02 - Data has been stored as ESCAPED 03 - To read the data and add its content to a TextBox where apply TinyMCE use in DATABOUND EVENT for DetailView and HttpUtility.HtmlDecode (so it will look decoded) 04 - You can modify content in the textbox in edit mode. On post back TinyMCE will encoded again using encoding: "xml" an so on Hope guys can help some one else. But please give me your comment on this solution thanks! Mybe you come up with more elegant solution! :-)

  • How can I stop a movie (from current frame) playing when I click on next frame - FLASH CS4?

    - by ladygeekgeek
    I have four movie clips (.f4v) in 4 frames in a movie with watch buttons.. This movie has them been imported into a main movie container that has next and previous buttons. However if i play a movie then hit next frame, the movie continues to play in the background. How can I shop this? The code below shows one of the actionscripts for a movie clip and then the main actionscript in the main movie. I am a flash newbie, so all help appreciated. Many thanks. stop(); watch1_btn.addEventListener(MouseEvent.CLICK, playMovie1); function playMovie1(event:MouseEvent):void { movie1_mc.play(); } // Button Listeners next_btn.addEventListener(MouseEvent.CLICK, nextSection); prev_btn.addEventListener(MouseEvent.CLICK, prevSection); function nextSection(event:MouseEvent):void { var thisLabel:String = pages_mc.currentLabel; // gets current frame label as string var thisLabelNum:String = thisLabel.replace("sct", ""); // cuts the leading letters off of the number var curNumber:Number = Number(thisLabelNum); // converts that string number to a real number if (curNumber < 5) { var nextNum:Number = curNumber + 1; // adds 1 to the number so we can go to next frame label pages_mc.gotoAndStop("sct" + nextNum); // This allows us to go to the next frame label } } /////////////////////////////////////////////////////////////////////////// function prevSection(event:MouseEvent):void { var thisLabel:String = pages_mc.currentLabel; // gets current frame label as string var thisLabelNum:String = thisLabel.replace("sct", ""); // cuts the leading letters off of the number var curNumber:Number = Number(thisLabelNum); // converts that string number to a real number var prevNum:Number = curNumber - 1; // subtracts 1 from the number so we can go to next frame label pages_mc.gotoAndStop("sct" + prevNum); // This allows us to go to the previous frame label }

  • Ridiculously Simple Erlang Question

    - by Aiden Bell
    Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and is there any guarantee of order when processing messages? ie. Received in order sent? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

  • Rails can't find my route but it exists!

    - by DJTripleThreat
    Ok I have events that I want to publish/unpublish with an extra action (nonRESTful) I watched Ryan Bates' railscast on this: http://railscasts.com/episodes/35-custom-rest-actions and it got me most of the way. I think the problem is that my route is nested in an /admin section so even though when I run rake routes and get: publish_admin_event PUT /admin/events/:id/publish(.:format) {:controller=>"event_services", :action=>"publish"} This won't work in my /views/admin/index.html.erb file: <%= link_to 'Publish', publish_admin_event(event), :method => :put %> because it claims that path doesn't exist! And neither will this: <%= link_to 'Publish', {:controller => :event_services, :action => :publish}, {:method => :put, :id => event} %> and says that "No route matches {:controller=>"event_services", :action=>"publish"}" so what gives? (And I've tried restarting my server so that isn't it.) EDIT: This DOES work: <%= link_to 'Publish', "/admin/events/" + event.id.to_s + "/publish", :method => :put %> But I'd rather NOT do this.
